Application December 21. 1935, Serial No. 55,632 Renewed January 11, 1937 3 Claims. (01. 90-9-19) This invention relates to improvements in low slugging mechanism.

The principal object of this invention is to provide means for low slugging a slug of type 5 commonly ejected from a line of type casting machine.

A further object is to provide means for automatically accomplishing this low slugging during the movement of the slug from the line casting machine in contradistinction to the customary hand routing or low slugging.

A further object is to produce a device of this character which is economical to manufacture and one which may be readily attached to a line of type machine.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a fragmentary top plan view of our low slugging mechanism;

Fig. 2 is a cross sectional view taken on, the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary front elevation;

Fig. 4 is a side elevation of a slug after trimming and showing in broken lines the trimmed 30 out material; and

Fig. 5 is an enlarged detail cross section taken on the line 5--5 of Fig. 4..

Slugs issuing from a line of type casting machine carry upon the upper surface a plurality 135 of characters which are usually grouped so as '4 the space between the words and cause a smudge or offset. Therefore, it becomes necessary to rout out or remove the metal in these spaces.

1 This routing is commonly known as low slugging and is accomplished usually by employing a hand driven rotary tool which is manually guided. This operation is, of course, tedious, slow, and unless the operator is exceedingly careful many lines of slugs are spoiled and must be recast, thus delaying the operation.

' With our device we propose to receive the slug from a line casting machine and during its move ment through the machine to operate upon the slug so as to remove this excessive metal.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 5 designates a channel into which the slug is ejected from the line casting machine. This slug is then engaged by a finger 6 of a feeding mechanism, which finger engages the back of the slug as at l, which slug is designated at 8. As the slug proceeds through the mechanism it first engages a roller 9 mounted upon a reciprocating arm H which is normally held down by a spring l2. This arm in turn has a hooked extremity 13 which engages a movable switch contact M. This switch contact is adapted to engage the contact IS, the purpose of which will be later seen. Mounted directly in front of the roller 9 and in alignment with the end movement of the slug 8 is a cutter head ll mounted upon a spindle l8. This spindle is splined to a gear 19 meshing with a driving gear it, which gear it may be driven in any desired manner. The spring 22 normally maintains the cutter ll in its dotted line position, and it is only moved downwardly when. the armature arm 23 is attracted by the solenoids 24 and these solenoids are only energized when the roller 9 engages a depression and drops from its dotted line position of Fig. 2 to its full line position, thus causing the hooked end l3 to move the contact M into engagement with the contact it, thus completing a circuit to the solenoids 2d.

The operation of our device is as follows. As a slug passes downwardly through the channel 5 its forward end will engage the roller 9, raising the same, breaking the circuit contacts l3 and Ml, thus deenergizing the solenoids 24 and releasing the armature arm 23. The spring It will immediately retract the cutter ll, and consequently when the type B reaches the position of the cutter no action will take place. The same will be true of the type C. However, when the space D is reached it is of sufficient width to permit the roller 9 to drop, thus establishing the circuit, energizing the solenoids, pulling upon the armature 23, and depressing the cutter which immediately cuts away the metal and continues to do so during the advancement of the slug in the direction of the black arrow of Fig. 2 or until the roller 53 engages the type at E. The same action will again take place when the slug reaches the point F.

Thus it will be seen that as We pass a slug through the machine it will be automatically cut or low slugged as above set forth.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, We claim:--

1. In a device of the character described, for use with a line casting machine, of a channel in alignment with the discharge of the line casting machine, whereby a slug therefrom will be received endwise, means for moving said received slug through said channel, a movable cutter mounted above said channel, and normally out of the path of movement of said slug, means for depressing said cutter into the path of movement of said slug said means being operated by the movement of said slug through said mechanism.

2. In a device of the character described, for use with a line casting machine, of a channel capable of receiving a slug discharged from the line casting machine, a movable roller in alignment with the path of movement of the slug through said channel, a rotary cutter mounted in close proximity to said roller, means carried by said roller for effecting a depression of said cutter when said roller is elevated.

3. In a device of the character described, for use with a line casting machine, of a channel capable of receiving a slug discharged from the line casting machine, a movable roller in alignment with the path of movement of the slug through said channel, a rotary cutter mounted in close proximity to said roller, means carried by said roller for effecting a depression of said cutter when said roller is elevated, and spring means for normally maintaining said cutter in elevated position out of the path of movement of the slug.
